Therefore, the problems of color change, blackening, lightening and the like of the ink image-text are not easy to occur in the use of the black paperboard after the printing ink.
In one embodiment, the black paperboard contains a black filler comprising carbon element, the black filler comprising 60% -70%. In other words, the black paperboard product of the present application is more preferably a black paperboard for carbon element, and the black filler accounts for 60-70% of the black paperboard, and such black paperboard is conventionally corroded by the fact that the printing ink is directly printed on the surface of the black paperboard because the black paperboard presents acidity. The application can play waterproof and ink-proof effects better through forming the styrene-acrylic emulsion touch layer on the upper surface of the black paperboard, so that the ink and the black paperboard can be well isolated, and the problems of color change, blackening, fading and the like of the ink image-text in use after the printing ink is used for a long time are solved.
In one embodiment, the styrene-acrylic emulsion touch layer comprises the following components in percentage by mass: 20-60% of styrene-acrylic emulsion, 5-15% of water-based resin, 1-2% of auxiliary agent and the balance of water. In one embodiment, the auxiliary agent includes at least one of a dispersant, a leveling agent, a slip agent, a defoamer, an anti-slip agent, a matting agent, a plasticizer, an anti-wear agent, and a pattern agent. In this embodiment, the auxiliary agent may be any auxiliary agent commonly used in the printing ink technical field. Dispersants, leveling agents, slip agents, defoamers, slip agents, matting agents, plasticizers, antiwear agents and patterning agents may also be employed as some agents known in the art. This application is not described in detail herein. For example, dispersants: the functional high molecular polymer or the functional small molecular compound is mainly used for dispersing pigment in a system, and can improve the tinting strength, shorten the grinding time of the ink, improve the stability of the system, prevent flooding, prevent flowery and the like. Leveling agent: the method is mainly used for leveling and continuously acting on the high polymer organic silicon ink layer, and the flowing property of the ink is enhanced. Slip agent: the surface of the printed ink layer is smooth and wear-resistant. Defoaming agent: for preventing and eliminating air bubbles during ink production and use. Anti-slip agent: the printing ink is used for printing packages with anti-slip requirements, especially cartons and packaging bags. Matting agent: for packages printed with matt and matt requirements. And (3) a plasticizer: is used for softening the ink layer and preventing the ink layer after printing from cracking. Wear-resistant agent: for providing abrasion resistance of the ink layer surface and blade compliance. Pattern agent: for producing different crack lines. In this embodiment, the styrene-acrylic emulsion touch layer comprises the following components in percentage by mass: the touch layer of the styrene-acrylic emulsion prepared by the method can play a good role in preventing oil films and corrosion, so that the problems of color change, blackening, lightening and the like of ink pictures and texts are not easy to occur in the use of black paperboard after printing ink. In particular, the coating formed after curing can better play a role in blocking by combining 20-60% of styrene-acrylic emulsion and 5-15% of aqueous resin, the blocking has waterproof and corrosion-resistant effects, the coating film after curing the touch oil ensures that the surface of paper is finer and smoother, and the touch oil contains 20-60% of styrene-acrylic emulsion and 5-15% of aqueous resin, so that the waterproof and oil-proof ink effects and the corrosion-resistant effects can be simultaneously considered when the touch oil is cooperatively combined, and the excellent corrosion-resistant effect is formed.
In one embodiment, the oil loading amount of the mixed components of the styrene-acrylic emulsion touch layer on the black paperboard is 4-6 g/m 2 . Therefore, the styrene-acrylic emulsion touch layer with the oil quantity can better achieve the effects of water resistance, oil resistance, ink resistance and corrosion resistance, and has excellent corrosion resistance, and the thickness of the styrene-acrylic emulsion touch layer can be relatively thinner. The applicant has found that when the oil loading is less than 4g/m 2 When the ink is used for a long time, the problems of discoloration, blackening, lightening and the like caused by corrosion of the ink still exist potentially. The oil loading amount of the mixed components passing through the touch layer of the styrene-acrylic emulsion on the black paperboard is 4-6 g/m 2 Namely, the anti-corrosion coating can have a better long-time anti-corrosion effect. And when the oil loading is greater than 4g/m 2 In the case of a latent image layer, the latent image layer may be not tight, thereby affecting the ink efficiencyAnd (5) fruits. When the oil quantity of the mixed components of the styrene-acrylic emulsion touch layer on the black paperboard is 4-6 g/m 2 In this case, the anti-corrosion effect and the ink printing effect can be well combined.

Therefore, the mixed components of the styrene-acrylic emulsion touch layer can form the styrene-acrylic emulsion touch layer after being cured, and the anti-corrosion effect is good.
In one embodiment, the black paperboard product further includes an ink layer formed on the surface of the styrene-acrylic emulsion tactile layer. For example, the ink layer is an environmentally friendly aqueous ink layer. For example, the ink layer comprises the following components in parts by mass: 20-25% of water-based resin, 1-3% of auxiliary agent, 25-30% of pigment, 2-5% of connecting material and the balance of water. Thus, the ink layer can be printed on the surface of the styrene-acrylic emulsion touch layer solidified coating better by adopting the ink layer. In this embodiment, the auxiliary agent includes at least one of a dispersant, a leveling agent, a slip agent, a defoaming agent, an anti-slip agent, a matting agent, a plasticizer, an anti-wear agent, and a pattern agent. Specifically, the binder, also known as a binder or adhesive, is the fluid portion of the ink and is also the primary component of the ink printing. The pigment such as pigment or dye can be suspended in the binder so that the pigment can be coated on the surface of the printing material. Meanwhile, the binder also plays a role in protecting the pigment, so that the pigment is not easy to precipitate or separate. The binder also has an important influence on the drying speed, adhesion, water resistance, light resistance, heat resistance, and the like of the printed matter. The binder in this application may be some binders common in the ink field, and is not described herein in detail. In one embodiment, the ink layer has a thickness of 1-2 μm. Thus, the oil-up amount on the black paperboard of the mixed components combined with the styrene-acrylic emulsion touch layer is 4-6 g/m 2 Namely, the anti-corrosion coating can have a better long-time anti-corrosion effect.
In one embodiment, the viscosity of the mixed components of the water-based ink layer is 10-25 Pa.S; 35-40% of solid content (Wt%); the pH value is 8.5-9; printing an anilox roller: 300-600 lines; temperature: 15-40 ℃; the thickness is 1-2 mu m. In this way, the ink layer can be formed well.

The styrene-acrylic emulsion touch layer has the characteristics of matte gloss, good wear resistance, excellent anti-sticking performance, environment friendliness, fine hand feeling and the like. According to the comparison test result, only one layer of treatment is carried out on the surface of the paper to form a barrier between the ink and the black paperboard, the barrier has the waterproof and corrosion-resistant effects, the surface of the paper is finer and smoother by the coating film after the touch oil is solidified, the touch oil contains the styrene-acrylic emulsion and the water-based resin, the styrene-acrylic emulsion has the waterproof and oil-resistant effects, and the coating film after the water-based resin is solidified has the corrosion-resistant effects to form the excellent corrosion-resistant effects.
